Description

Method and equipment for discontinuous reception

Technical field

The embodiments of the present application relate to the field of communications, and more specifically, to a method and device for discontinuous reception (DRX).

Background technique

In consideration of power saving of terminal equipment, DRX mechanism is introduced. The network device can configure the terminal device to "wake up" at the time predicted by the network device and monitor the downlink control channel when it wakes up. It can also configure the terminal device to "sleep" at the time predicted by the network device and not monitor the downlink control channel during sleep. In this way, if the network device has data to be transmitted to the terminal device, the terminal device can be scheduled during the wake-up time of the terminal device, and the terminal device can reduce power consumption during the sleep time.

Although the network configures the DRX mechanism for the terminal equipment to periodically wake up the terminal equipment to detect the downlink control channel, but the terminal equipment is only scheduled opportunistically during the wake-up period, even when the terminal equipment is under low traffic load. It will be scheduled only in a few DRX cycles. For paging messages that adopt the DRX mechanism, the terminal has fewer opportunities to receive the paging message. Therefore, after the terminal device is configured with the DRX mechanism, it may not be able to detect the control channel but still be awakened during most of the awakening period, which increases unnecessary power consumption.

The small cell here may include: Metro cell, Micro cell , Pico cells, Femto cells, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-rate data transmission services.

Fig. 1 exemplarily shows one network device and two terminal devices, but the application is not limited to this. The wireless communication system 100 may include a plurality of network devices, and the coverage area of each network device may include other numbers of terminal devices. In addition, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity.

The DRX mechanism can make the terminal device enter the sleep state periodically at certain times, without monitoring the Physical Downlink Control Channel (PDCCH), and wake up from the sleep state when it needs to monitor the PDCCH, so that the terminal The equipment achieves the purpose of saving electricity.

Figure 2 is a schematic diagram of a typical DRX cycle (DRX Cycle). As shown in Figure 2, the T1 period is the wake-up time of the terminal device, called On Duration, and the T2 period is the sleep time of the terminal device, called DRX opportunity (Opportunity for DRX). The network device can configure a DRX duration timer (drx-onDurationTimer) for the terminal device to control the wake-up time of the terminal device, and the timing duration of the DRX duration timer is T1. The terminal device needs to continuously monitor the PDCCH during the wake-up time T1, but does not monitor the PDCCH during the sleep time T2. The longer the T2 time, the lower the power consumed by the terminal equipment, but correspondingly, the delay of service transmission will increase accordingly. To this end, in addition to the DRX duration timer, the network device also configures other DRX timers for the terminal device to adjust the wake-up time of the terminal device.

For example, the DRX inactivity timer (drx-InactivityTimer) indicates how long the terminal device needs to continue monitoring after successfully detecting the PDCCH.

For another example, the DRX downlink retransmission timer (drx-RetransmissionTimerDL) is used for the terminal device to receive the downlink retransmission service, which indicates the length of time that the terminal device needs to continuously monitor in order to receive the desired downlink retransmission service. Correspondingly, the DRX uplink retransmission timer (drx-RetransmissionTimerUL) is used for the uplink retransmission service of the terminal equipment.

For another example, DRX (Hybrid Automatic Repeat reQuest, HARQ) round-trip time (Round-Trip Time, RTT) timer (HARQ-RTT-TimerDL) is used by terminal equipment to receive downlink retransmission services, indicating that terminal equipment The length of time to wait before receiving the expected downlink retransmission service. Correspondingly, the DRX uplink HARQ round trip time timer (HARQ-RTT-TimerUL) is used for the uplink retransmission service of the terminal equipment.

In addition, the network device may also configure a random access contention resolution timer (ra-ContentionResolutionTimer), a DRX short cycle timer (drx-ShortCycleTimer), and other DRX timers for the terminal device.

Taking FIG. 3 as an example, during the timing of the DRX duration timer (drx-onDurationTimer), the terminal device monitors the PDCCH. If the terminal device detects that the PDCCH indicates new downlink data during the timing of the DRX duration timer, it starts the DRX inactivity timer (drx-InactivityTimer). Among them, a transmission of new downlink data indicates the beginning of a HARQ process. The terminal device receives the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) according to the downlink control information (downlink control information, DCI) in the PDCCH.

The terminal device carries HARQ feedback information to the network device in a physical uplink control channel (PUCCH) or a physical downlink shared channel (PUSCH). The terminal device starts the downlink HARQ round trip time timer (HARQ-RTT-TimerDL) of the corresponding HARQ process at the first symbol after sending all the symbols of the PUCCH or PUSCH carrying the HARQ feedback information.

When the downlink HARQ round trip time timer expires, if there is a transport block (TB) that fails to decode the PDSCH previously received, the terminal device will start the DRX downlink retransmission timer (drx-RetransmissionTimerDL). During the timing of the DRX downlink retransmission timer, the terminal device is in Active time and blindly detects the PDCCH. If retransmission of DCI is detected, it stops the DRX downlink retransmission timer and receives the PDSCH based on the retransmission DCI. If all the previously received PDSCHs are successfully decoded, the terminal device does not start the DRX downlink retransmission timer.

Although the above DRX mechanism allows the terminal device to monitor the PDCCH only during a part of each DRX cycle, the terminal device may only be scheduled in a few DRX cycles, and the PDCCH cannot be detected in most DRX cycles. Will be awakened, which increases unnecessary power consumption.

To this end, the embodiment of the application proposes that the network device can send a wakeup signal (Wakeup Signal, WUS) to the terminal device within a preset time period before the start time of the DRX duration timer, and use the wakeup signal to indicate whether the terminal device needs to be The DRX duration timer is started at this starting time. In this way, if the network device schedules data to the terminal device, the wake-up signal can instruct the terminal device to start the DRX duration timer as usual at the start time, so as to wake up the terminal device to monitor the PDCCH; if the network device does not schedule data for the terminal device, The wake-up signal can be used to instruct the terminal device not to start the DRX duration timer, so that the terminal device does not have to be waked up, thereby further reducing the power consumption of the terminal device.

However, if there are other DRX timers running at this time, whether the terminal device needs to start the DRX duration timer and how to process other running DRX timers has also become a problem to be solved.

For this reason, the embodiment of the present application proposes a discontinuous reception method, which can ensure the effective operation of each DRX timer in the DRX process, thereby further reducing the power consumption of the terminal device.

FIG. 4 is a schematic flow interaction diagram of discontinuous reception according to an embodiment of the present application. The method shown in FIG. 4 may be executed by a terminal device and a network device. The terminal device may be, for example, the terminal device 120 shown in FIG. 1, and the network device may be, for example, the network device 110 shown in FIG. 1. As shown in Figure 4, the discontinuous reception method includes:

In 410, the network device determines whether the terminal device needs to start a DRX duration timer (drx-onDurationTimer) in the DRX cycle after the first period of time.

If the network device determines that the terminal device needs to start the DRX duration timer, then execute 420; and/or if the network device determines that the terminal device does not need to start the DRX duration timer, then execute 420.

In 420, the network device sends a wake-up signal WUS to the terminal device in the first period.

In 430, the terminal device detects the wake-up signal in the first time period.

If the terminal device detects the wake-up signal, execute 440; if the terminal device does not detect the wake-up signal, execute 450.

In 440, the terminal device starts the DRX duration timer in the DRX cycle after the first period of time.

In 450, the terminal device does not start the DRX duration timer in the DRX cycle after the first time period.

In this embodiment, the network device instructs the terminal device whether to start the DRX duration timer at the appointed time by sending a wake-up signal, and the terminal device determines whether the DRX cycle after the wake-up signal is required according to whether the wake-up signal sent by the network device is detected Start the DRX duration timer in the middle, so that there is no need to wake up and monitor the PDCCH without waking up, thus further reducing the power consumption of the terminal device during the DRX process.

The DRX duration timer is used to control the duration of the DRX cycle (On Duration). The start time of the DRX duration timer is the start time of the T1 period in Figure 2 and Figure 3, and the end time of the DRX duration timer That is, the end time of the T1 period in Figure 2 and Figure 3.

For example, as shown in FIG. 5, the first time period may be located before the T1 time period for transmitting the wake-up signal. Whether the wake-up signal is sent or not can be used to indicate whether the terminal device needs to wake up in the T1 period, or in other words, to indicate whether the DRX duration timer needs to be started at the start position of the T1 period.

If the terminal device detects the wake-up signal in the first time period, it will start the DRX duration timer at the appointed time, that is, at the beginning of the T1 time period, and wake up within the time period of the DRX duration timer, that is, the T1 time period. Monitor the PDCCH; if the terminal device does not detect the wake-up signal in the first time period, it does not need to start the DRX duration timer, but keeps the sleep state during the T1 time period.

The network device may send instruction information to the terminal device, where the instruction information is used to indicate the first time period, for example, used to indicate the position and/or length of the first time period relative to the T1 period, so that the terminal device receives the instruction information to The first time period is acquired, and the wake-up signal is detected in the first time period. The indication information may be, for example, radio resource control (Radio Resource Control, RRC) signaling, medium access control (Medium Access Control, MAC) signaling, or DCI.

Alternatively, the first time period may also be agreed upon by agreement.

If the network device has data to be sent to the terminal device, it sends a wake-up signal to the terminal device, thereby instructing the terminal device to start the DRX duration timer in the next DRX cycle, so that the terminal device wakes up and receives data; if the network device does not The data to be sent does not send a wake-up signal to the terminal device, thereby instructing the terminal device not to start the DRX duration timer in the next DRX cycle, and the terminal device can continue to stay in a sleep state, saving the power consumption of the terminal device.

It should be understood that in the embodiment of the present application, whether the wake-up signal is sent in the first time period can be used to indicate whether the terminal device starts the DRX duration timer in a DRX cycle after the first time period, and can also be used to Instruct the terminal device whether to start the DRX duration timer in multiple consecutive DRX cycles after the first period.

Since other DRX timers other than the DRX inactivity timer may be running in the first time period, the terminal device needs to determine whether to stop these running DRX timers.

Optionally, the method further includes: if the terminal device does not detect the wake-up signal, and the running DRX-Inactivity Timer (drx-InactivityTimer) has not stopped in the first time period, continue running or stop the DRX inactivation timer; and/or, if the terminal device detects the wake-up signal and the running DRX inactivation timer has not stopped in the first time period, continue to run the DRX inactivation timer.

Optionally, the method further includes: if other DRX timers that are running in the first time period have not stopped, the terminal device continues to run the other DRX timers.

Among them, the other timers mentioned here include, for example, at least one of the following DRX timers: DRX downlink retransmission timer (drx-RetransmissionTimerDL), DRX uplink retransmission timer (drx-RetransmissionTimerUL), DRX short cycle timer (drx-ShortCycleTimer), DRX downlink HARQ round trip time timer (HARQ-RTT-TimerDL), DRX uplink HARQ round trip time timer (HARQ-RTT-TimerUL), random access contention resolution timer (ra-ContentionResolutionTimer), etc.

This embodiment is further described in combination with the following two situations.

Situation 1

If the terminal device detects the wake-up signal in the first time period, and the running DRX timers in the first time period have not stopped, the terminal device needs to continue to run these DRX timers.

For example, if the terminal device detects the wake-up signal in the first time period and the DRX inactivation timer that is running in the first time period has not stopped, the terminal device starts DRX continuation in the DRX cycle after the first time period. Time timer, and continue to run the DRX inactive timer.

For another example, if the terminal device detects the wake-up signal in the first time period, and other DRX timers that are running in the first time period have not stopped, the terminal device starts the DRX continuation in the DRX cycle after the first time period. Time timer, and continue and keep these running DRX timers, such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip At least one of time timer, random access contention resolution timer, etc.

This is because the network device sends the wake-up signal to the terminal device, indicating that the network device has data to be transmitted. At this time, the terminal device not only needs to start the DRX duration timer at the appointed time, but also needs to keep other DRX timers currently running.

Situation 2

If the terminal device does not detect the wake-up signal, and the running DRX timer has not stopped in the first time period, the terminal device can stop some or all of these DRX timers, or continue to maintain these DRX timings Device.

For example, if the terminal device does not detect the wake-up signal and the DRX inactivation timer that is running in the first time period has not stopped, the terminal device does not start the DRX duration timer and stops the DRX inactivation timer Device.

For another example, if the terminal device does not detect the wake-up signal, and the running DRX inactivation timer has not stopped in the first time period, the terminal device does not start the DRX duration timer and continues to run the DRX non-activation timer. Activate the timer.

For another example, if the terminal device does not detect the wake-up signal in the first time period, and other DRX timers that are running in the first time period have not stopped, the terminal device does not start the DRX duration timer and keeps running These running DRX timers, for example, include DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip time timer, random access contention resolution At least one of timers, etc.

First, for the DRX inactivation timer, when the terminal device does not detect the wake-up signal, it can stop or continue to keep the running DXR inactivation timer.

On the one hand, considering that the trigger mode of the DRX inactive timer is started or restarted based on the new transmission schedule, sometimes the network device only has one scheduling, and the time when the DRX inactive timer is restarted later will not schedule data for the terminal device. Up. In addition, if the terminal device learns that the DRX duration timer does not need to be started during the operation of the DRX inactivity timer, it indicates that the network device has no data to provide to the terminal device at this time, and it is not necessary to maintain the DRX inactivity timer. Therefore, if the terminal device does not detect the wake-up signal and the running DRX inactivation timer has not stopped, the terminal device can choose to stop the DRX inactivation timer.

On the other hand, there may be two situations where the terminal device does not detect the wake-up signal. One is that the network device does not send the wake-up signal, and the other is that the network device sends the wake-up signal but the terminal device misses the detection. The terminal equipment is not clear about these two situations. If the DRX inactivation timer is still running in the first period, it means that the terminal device is still in the active time (Active time). Therefore, if the terminal device does not detect the wake-up signal, and the running DRX inactivation timer has not stopped, the terminal device can choose to continue to maintain the running DRX inactive timer, so that there are problems when the wake-up signal is missed. Opportunity to receive PDCCH.

Secondly, for other DRX timers such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip time timer, etc., starting these timers indicates that there is retransmission at this time. Scheduling, so these timers need to keep running. In addition, continuing to keep these DRX inactive timers running can enable the terminal device to have a chance to receive the PDCCH when the wake-up signal is missed.

Optionally, the method further includes: if the terminal device is in an active time (Active time) after sending the SR within the first time period, the terminal device continues to maintain the active time.

For example, when the terminal device does not detect the wake-up signal, if the terminal device finishes sending a reference signal (Reference Signal, SR) and the SR is in the pending state, the terminal device needs to be in the activation time, then the terminal device continues to maintain the activation time.

Optionally, the method further includes: if the terminal device does not detect the wake-up signal within the first time period, starting a first timer; if the terminal device still does not detect wake-up within the time period of the first timer Signal, start the DRX duration timer in the DRX cycle after the first timer expires; and/or, if the terminal device detects the wake-up signal within the time period of the first timer, it stops the first timer A timer.

When the terminal device does not detect the wake-up signal, one situation is that the network device does not send the wake-up signal, and the other situation is that the network device sends the wake-up signal but the terminal device misses the detection. In the latter case, it may be due to the poor current signal quality of the terminal device, such as the terminal device being at the edge of the cell, etc., resulting in the terminal device being unable to start the DRX duration timer because it fails to detect the wake-up signal, which will affect Data scheduling performance.

Therefore, when the terminal device does not detect the wake-up signal in the first time period, the DRX duration timer is not started in the next DRX cycle, and the first timer is started. If the terminal device never detects the wake-up signal within the time duration of the first timer, then when the timer expires, even if the terminal device does not detect the wake-up signal, the terminal device needs to start the DRX duration timer. If the terminal device detects a wake-up signal during the timing of the timer, it stops the first timer.

In this way, it is possible to avoid the situation that the terminal device cannot start the DRX duration timer for a long time because it fails to detect the wake-up signal.

The configuration information of the first timer, such as the timing duration, etc., may be notified by the network device to the terminal device, or agreed upon by the protocol.

The embodiment of the present application does not limit the timing duration of the first timer. For example, the timing duration of the first timer may be greater than the length of one or several DRX cycles.

Fig. 6 is a schematic flow interaction diagram of discontinuous reception according to an embodiment of the present application. The method shown in FIG. 6 may be executed by a terminal device and a network device. The terminal device may be, for example, the terminal device 120 shown in FIG. 1, and the network device may be, for example, the network device 110 shown in FIG. 1. As shown in Figure 6, the discontinuous reception method includes:

In 610, the network device sends a wake-up signal WUS to the terminal device in the first period.

The wake-up signal is used to indicate whether the terminal device starts the DRX duration timer in the DRX cycle after the first time period.

In 620, the terminal device detects the wake-up signal in the first time period.

If the terminal device detects the wake-up signal, and the wake-up signal is used to instruct the terminal device to start the DRX duration timer in the DRX cycle after the first period of time, the terminal device executes 630; and/or,

If the terminal device detects the wake-up signal and the wake-up signal is used to instruct the terminal device not to start the DRX duration timer in the DRX cycle after the first period of time, the terminal device executes 640; and/or,

If the terminal device does not detect the wake-up signal, execute 630.

In 630, the terminal device starts the DRX duration timer (drx-onDurationTimer) in the DRX cycle after the first period of time.

In 640, the terminal device does not start the DRX duration timer in the DRX cycle after the first time period.

In this embodiment, the network device sends a wake-up signal to indicate whether the terminal device needs to start the DRX duration timer at the appointed time, and the terminal device determines whether it needs to start the DRX duration in the DRX cycle after the wake-up signal according to the detected wake-up signal Time timer, so that there is no need to wake up to monitor the PDCCH when there is no need to wake up, thus further reducing the power consumption of the terminal device in the DRX process.

In the aforementioned method shown in Figure 4, the network device instructs the terminal device whether to start the DRX duration timer by sending a wake-up signal, while in the method shown in Figure 6, the network device sends a wake-up signal to the terminal device and passes The content of the wake-up signal indicates whether the terminal device starts the DRX duration timer.

The DRX duration timer is used to control the duration (On Duration) in the DRX cycle. The start time of the DRX duration timer is the start time of T1 in Figures 2 and 3, and the end time of the DRX duration timer is The end time of T1 in Figure 2 and Figure 3.

For example, as shown in FIG. 5, the first time period may be located before the T1 time period for transmitting the wake-up signal. The wake-up signal may be used to indicate whether the terminal device needs to wake up in the T1 period, or in other words, to indicate whether the DRX duration timer needs to be started at the start position of the T1 period.

If the terminal device detects the wake-up signal in the first period and the wake-up signal instructs the terminal device to start the DRX duration timer, or the terminal device does not detect the wake-up signal in the first period, the terminal device is at the beginning of the T1 period Start the DRX duration timer, and wake up and monitor the PDCCH within the T1 period of the DRX duration timer; if the terminal device detects a wake-up signal in the first period and the wake-up signal instructs the terminal device not to start DRX With the duration timer, the terminal device does not need to start the DRX duration timer, but keeps the sleep state during the T1 period.

The network device may send instruction information to the terminal device, where the instruction information is used to indicate the first time period, for example, used to indicate the position and/or length of the first time period relative to the T1 period, so that the terminal device receives the instruction information to The first time period is acquired, and the wake-up signal is detected in the first time period. The indication information may be, for example, RRC signaling, MAC signaling, or DCI.

Alternatively, the first time period may also be agreed upon by agreement.

If the network device has data to be sent to the terminal device, it sends a wake-up signal to the terminal device, and the wake-up signal instructs the terminal device to start the DRX duration timer in the next DRX cycle, so that the terminal device wakes up and receives the data; network If the device has no data to be sent, it sends a wake-up signal to the terminal device, and the wake-up signal indicates that the terminal device will not start the DRX duration timer in the next DRX cycle, so the terminal device can continue to stay in the sleep state, saving the terminal device Power consumption.

For example, the wake-up signal may include first information, and the first information may occupy one bit. When the value of the bit is 1, it indicates that the terminal device needs to start the DRX duration as usual in the DRX cycle after the first period of time. Timer: When the value of this bit is 0, it means that the terminal device does not start the DRX duration timer.

The wake-up signal in the first time period can be used to instruct the terminal device whether to start the DRX duration timer in a DRX cycle after the first time period, or it can be used to instruct the terminal device to indicate multiple consecutive DRX cycles after the first time period. Whether to start the DRX duration timer within, the embodiment of this application does not limit this.

The network device will send a wake-up signal to the terminal device in the first time period. Therefore, if the terminal device does not receive the wake-up signal, it means that the terminal device missed the wake-up signal. However, even if the terminal device knows that the wake-up signal is missed, it cannot determine whether the network device wants to wake it up. The terminal device still starts the DRX duration timer at the appointed time when the wake-up signal is not detected, to ensure scheduling performance and avoid missing data sent by the network device, although this may lose some power consumption.

Of course, in the embodiment of the present application, it is also possible to configure the terminal device not to start the DRX duration timer when the wake-up signal is not detected, thereby reducing the power consumption of the terminal device.

Optionally, the method further includes: if the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device to start the DRX duration timer in the DRX cycle after the first time period, and is in the first time period If the running DRX inactivity timer (drx-InactivityTimer) has not stopped, continue to run the DRX inactivity timer; and/or, if the terminal device detects the wake-up signal and the wake-up signal indicates that the terminal device is in the first period If the DRX duration timer is not started in the subsequent DRX cycle, and the DRX inactivation timer that is running in the first period has not stopped, continue to run or stop the DRX inactivation timer; and/or, if If the terminal device does not detect the wake-up signal, and the running DRX inactivation timer has not stopped in the first time period, it continues to run the DRX inactivation timer.

Wherein, the other timers mentioned here include, for example, at least one of the following DRX timers: DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time timer, DRX Uplink HARQ round-trip time timer, random access contention resolution timer, etc.

This embodiment is further described in combination with the following three situations.

Situation 1

If the terminal device detects the wake-up signal in the first period and the wake-up signal instructs the terminal device to start the DRX duration timer, and the running DRX timer has not stopped in the first period, the terminal device needs to continue to run these DRX timer.

For example, if the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device to start the DRX duration timer, and the DRX inactivity timer that is running in the first period has not stopped, the terminal device will Start the DRX duration timer in the DRX cycle of the DRX cycle, and continue to run the DRX inactive timer.

For another example, if the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device to start the DRX duration timer, and other DRX timers running in the first time period have not stopped, the terminal device is in the first Start the DRX duration timer in the DRX cycle after the time period, and keep these running DRX timers, such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time At least one of timer, DRX uplink HARQ round trip time timer, random access contention resolution timer, etc.

This is because the network device sends the wake-up signal to the terminal device and instructs the terminal device to start the DRX duration timer, which means that the network device has data to be transmitted. At this time, the terminal device not only needs to start the DRX duration timer at the appointed time, but also Need to keep other DRX timers currently running.

Situation 2

If the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device not to start the DRX duration timer in the DRX cycle after the first time period, and the DRX timer that is running in the first time period has not stopped , The terminal device can stop some or all of these DRX timers, or continue to maintain these DRX timers.

For example, if the terminal device detects the wake-up signal and the wake-up signal indicates that the terminal device does not start the DRX duration timer in the DRX cycle after the first period of time, the terminal device does not start the DRX duration timer and stops the running DRX Inactive timer.

For another example, if the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device not to start the DRX duration timer in the DRX cycle after the first period of time, the terminal device does not start the DRX duration timer, and keeps being Running DRX inactive timer.

For another example, if the terminal device detects the wake-up signal and the wake-up signal instructs the terminal device not to start the DRX duration timer in the DRX cycle after the first period of time, the terminal device does not start the DRX duration timer, and keeps being Running DRX timers, such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip time timer, random access contention resolution timing At least one of the devices.

For the same reason as the foregoing, the triggering method of the DRX inactivation timer is to start or restart based on the new transmission schedule. Sometimes the network device is only scheduled once, and the time for restarting the DRX inactivation timer will not be given to the terminal device. Schedule data. And if the wake-up signal received by the terminal device indicates not to start the DRX inactivation timer, indicating that the network device has no data to give to the terminal device at this time, it is not necessary to maintain the DRX inactivation timer. Therefore, when the terminal device detects the wake-up signal and the wake-up signal indicates that the DRX inactivation timer is not to be started, the terminal device can choose to stop the DRX inactivation timer in addition to keeping the running DRX inactivation timer.

Optionally, the wake-up signal may also include second information, which is used to indicate whether to continue running or stop the DRX inactivation timer running in the first time period.

After the terminal device receives the wake-up signal, if the second information in the wake-up signal indicates to stop the running DRX inactive timer, the terminal device stops the DRX inactive timer; if the second information in the wake-up signal indicates to continue If the DRX inactive timer is run, the terminal device keeps the DRX inactive timer running.

In addition, the wake-up signal can also be used to indicate whether other DRX timers such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip time timer and other DRX timers are needed stop.

Situation 3

If the terminal device does not detect the wake-up signal and the DRX timers that are running in the first time period have not stopped, the terminal device needs to continue to run these DRX timers.

For example, if the terminal device does not detect the wake-up signal in the first time period, and the DRX inactivation timer that is running in the first time period has not stopped, the terminal device starts DRX continuation in the DRX cycle after the first time period. Time timer, and continue to run the DRX inactive timer.

For another example, if the terminal device does not detect the wake-up signal in the first time period, and other DRX timers that are running in the first time period have not stopped, the terminal device starts DRX continuation in the DRX cycle after the first time period Time timer, and continue and keep these running DRX timers, such as DRX downlink retransmission timer, DRX uplink retransmission timer, DRX short cycle timer, DRX downlink HARQ round trip time timer, DRX uplink HARQ round trip At least one of time timer, random access contention resolution timer, etc.

Optionally, the method further includes: if the terminal device is in the active time (Active time) after sending the SR within the first time period, the terminal device continues to maintain the active time.
